Router keeps losing connection to cable modem

Q: Router keeps losing connection to cable modem

About every 1-2 weeks my router loses the connection to the internet via cable modem. This has happened with 2 different cable modems (Netgear CM212 and Motorola Surfboard 5100) and also with 2 different routers (Netgear 614 and D-Link DI-524). When this happens the thing that usually fixes it is unplugging the router for several minutes and then plugging it back in again. I have Windows XP set to automatically detect the internet connection, and the router is set to use DHCP. Sometimes I also have to bypass the router and then put it back (so this could be partially a Windows problem?). Is there any way I can configure the router so it doesn't keep losing the internet connection? I have Comcast cable modem service.

Thank you.

I have a friend who has cable modem and Yahoo ISP. They continually get knocked offline and have to refire the internet. I know computers but have no experience with cable modems as I am stuck in 26.4 dial up land. The cable company says all is well on there end, they replaced her cable box for this problem before that. I don't use yahoo as an isp but do use their chat messenger to chat with this friend. I don't get knocked off. Any ideas? Her Computer is Hewlitt Packard, poor girl, and no older than six months.

I am on 512k Broadband here in UK. For what its worth I find Yahoo very slow (except the homepage). I have an email acct. with them purely to take most of my spam - and its very slow to load both the inbox, and the individual emails contained therein.

If your friend wants to test her connection for data loss or other faults, if only for peace of mind then recommend she looks at these sites as they have tests and can give you suggested tweaks based on the findings :

I have a motorola SB5120 surfboard modem, an adelphia cable internet connection, and a DLINK - DI-514 wireless router. When I connect my modem directly to my computer, the internet connection works fine. When I connect to my router, it will work for like 5 minutes and then just lose the connection "can't find server". A few weeks ago, everything was fine, but since I just got this new modem, I don't know if its the modem or if it's the router -- if I need to replace either.

I have tried the renew and release, I've tried resetting the modem, uploading the new firmware. DLiNK tells me something on my computer is blocking the signal -- a firewall because there are always all the lights on my modem when I'm connected directly and when I'm connected through the router.

i must also mention that there are times when i'm connected directly to the computer and not the router, i also lose the connection -- even with all the lights on -- that I have to do a renew/release.

I hope that you can help me figure this out.

A:DLINK losing connection/cable modem

Curious to know if you reset the D-Ling back to factory setting and start from scratch with the setup? If you didn't you may have some setting in there preventing the router from obtaining the info from the modem.

Try resetting the router, then turn everything off. Start by turning the modem on, let it stabilize, then the router...give it a couple of minutes and then the computer.

I have a motorola surfboard cable modem from time warner connected to Linksys WRT54G router, with one wired connection to the PC and a wireless connection to a laptop.

The connection to the internet is dropped every couple of hours from both computers and requires me to unplug the cable modem and then the router and then plug them back in before it will work again.

When the connection does drop, I cannot even access the router setup ( from the PC. Also, this problem did not seem to happen when I tried connecting the PC right to the cable modem without the use of the router. This is why I think it is the router.

I tried setting the router to clone MAC address, and setting the MTU to 1400, but I am still having the same problem. Does anyone have other suggestions about what else there is to do?

A:WRT54G Router dropping connection to cable modem

First things we normally recommend are:
Download the latest firmware for your router.
Reset your router to it's default config by holding in the reset button for at least 15 seconds.

Ok here's the situation:
I just moved into a student apartment. The internet is already activated and it is available through the RJ45 jack straight off the wall. Using an Ethernet cable I am able to use Internet without any issues with my PC.

What I want to do:
- Use my Buffalo ADSL router/modem to share the connection: both wired and wireless.
- Use my router as local DHCP to create a private network with my home devices.
- Be able to access both the internet and the router without having to unplug anything.

The setup:
- There is no way to use a DSL (phone) cablein the house so I have to plug the Ethernet cable carrying the connection in one of the LAN port of the router.
- My PC use another free LAN port.

The issues so far:
- I am only able to share the connection through the LAN ports of the router.
- Wireless devices are able to connect (it even read "Internet access" in the tray bar) but are unable to browse. It can't resolve proxy and always time out.
-When the Ethernet cable is plugged into the router, the router itself becomes unavailable. I'm assuming the connection has its own gateway somewhere else and prevents me from accessing the router.
- I effectively don't have any private network anymore.

edit: another weird thing I noticed. On my laptop anytime I try to connect to a wireless network it connects to 2 networks at the same time. One with the proper SSID and the other "Unidentified network"

A week ago, my computer suddenly could not connect to the internet. I was using a cable directly connected to the cable modem.

Since then, I've tried:

1) Added a WiFi router connected to the cable modem. Tried using the WiFi card built in to the computer. It connects but reports "limited access", and there is no connection to the internet, and I can't access the router itself.

2) Bought a new Ethernet card, installed the drivers that came with it. I've tried it connected through the WiFi router's hard ports and directly to the modem. Hard resets (power cycling off 2 minutes) on the modem each time and still no connection.

3) In device manager, both Ethernet cards show as "working normally" with no errors. So does the WiFi card.

4) ipconfig shows only "tunneling" devices with media disconnected.

5) I've uninstalled and re-installed the drivers for the on-baord Ethernet, the WiFi card, and the new Ethernet card.

After reading some other posts, I captured the output from ipconfig and several netsh commands. I've attached them to this post. The files starting with netsh are basically the command entered with underscores replacing the spaces from the commands used to generate them.

I also borrowed another computer. It connects both directly through the cable modem, and using the Ethernet ports on the router. It doesn't have WiFi, so I couldn't test that method of access. It can also connect to and c... Read more

My Situation:

I completely loose my cable connection upon turning the computer off and restarting it, that is most of the time. Sometimes I can turn it off three or fours times and all is working; email, browser, download updates and such with no problem. When I look in the device manager when all is working I have network adapters under which I see the cable modem. No question or exclamation marks.

At the times I restart and there is no email or web access and I look into device manager I find that the network adapters is not there. I am using WinXP pro and a USB connection for the cable modem. When it is working I believe I have the icon that allows for safe removal of hardware. When it is no working this icon is not there. If I unplug and plug back in the USB cable nothing happens.

I appreciate any help you might offer and thank you in advance.

Hey guys,

I have an issue with my current network where every couple of hours I will lose my connectivity and it will not come back unless I do a power cycle on my router/modem. I originally thought the issue was with my router, however I'm beginning to think it's an issue involving the modem. I've tried two different routers and this happens on both. My main router is a D-Link WBR-1310 (crap I know but it was free) and has lasted for years, and my modem is a Toshiba PCX2500 from Time Warner Cable. The second router I used to test this was an older Linksys BEFW11S4. I was going to replace my router, but when I saw that both of them reset after a few hours (today was only 5, last night it was connected for over 8 hours as I slept). I ran an IPCONFIG /ALL when I was connected with internet and when I was connected without and the only three changes were:
IPv4 Address. . . . . . . . . . . :
Changed to:
Autoconfiguration IPv4 Address. . :
Default Gateway . . . . . . . . . :
DHCP Server . . . . . . . . . . . :

So I my laptop is upstairs and my At&t Uverse cable modem is downstairs and I believe there is some interference in the ceiling because although the signal always reads as "excellent" often times it seems to run a bit slower upstairs than when i bring it one floor down. I was wondering if connecting the laptop to the modem directly would be more helpful. (I already have a hidden wiring route that I made to run a hdmi cable from my tv downstairs to the laptop upstairs) I bought a 50ft cable cord and was wondering if all i need to do is plug it in or if i have to somehow program the connection so it knows to run through the cable instead of the wireless signal. I don't have a router either...not sure if id need one as they didn't provide one. Detailed help is much appreciated!

A:How do I set up a connection to a cable modem with a cable cord?

Just plug it in at both ends. It should work fine.

Once plugged in, it will take a few seconds to detect the new wired network and get an IP Address. After that you should be all set.

Edit: You can disable the Wireless if you want. There is either a switch on the laptop or a Fn+Fkey combination to do it.

Hello, i'm having a strange problem with my internet connection. When i plug the cable onto my notebook, the internet connects normally for about a minute or two, then, i lose internet connection, while the network is still up. On windows' log, the only redundant log i found was error 1014, in ''System'' type, showing basically that no DNS server configured responded, but i switched the DNS about 4 times, tried to put both DNS and IP automatic, but the error still occurs, and if i deactivate the network, unplug and plug again the cable on the notebook, or switch the cable entrance on the router, the connection comes back for about a minute or two, and again, lose it.. But the odd fact, is that the wireless connection is completely normal, i'm using wireless for about 5 days without a single loss of connection.
I recently upgraded my windows 8 to windows 10, and i don't know if this is the cause of the issue, because the problem appeared about 1 week after the upgrade.

My previous old winmodem died recently, causing me to get a new modem. I founda good deal on an Intel 536EP V.92 hardware Modem. I had no connection problems with my very old software modem, when I connected it could stay connected for as long as I wanted.

But with this new modem, I frequently lose my connection. Whether it's 5 minutes, 10 minutes, or 45 minutes, after a certain amount of time my connection dies. I'd thought it may be an issue with call waiting, but it happens regularly at any hour, and I've disabled it and it still dies. I've also tried an automatic pinging program, though I never needed one before.

The only changes between my internet being reliable and not is the change in modem, as well as I installed a program called Advanced System Optimizer. One of the tweaks it allows is to allow speeds up to 921600 kpbs for a 56 modem. I turned it on initially, but turned it off later when my connection decided to start dying. It doesn't seem to have any kind of affect on the stability of my connection.

Any suggestions?

Hi, I have a strange question that im hoping can work (for a fortnight at the most lol)

I have just joined Virgin Media on 20meg connection. They sent me out an Ambit E08C013.00 modem but forgot to send out the router. Then the engineer installs the wallbracket lobsided! But anyway, im getting away from my question.

I have to wait up to 2 weeks for my router and in the meantime, my computer is upstairs and my connection is downstairs! I dont want to buy a router that will last me 2 weeks, so I decided to dig out my old BT Voyager 2091 router. I connected it to my Netgear FS208 v2 ethernet network switch and now I am trying to get it to broadcast my BB signal from my Ambit modem (which is also connected to my Netgear switch)

I can now connect to my wireless router, but it will not broadcast my broadband.

Is there a way to fix this? Or do I have to wait till my new router arrives?

Hello everyone,
I have an internet connection problem and was wondering if anyone here can help.
I cannot connect to the internet even though all the green lights on the modem are solid and steady. I have a laptop connects (ethernet cable) to the modem (which connect to the ISP). I ask my ISP support to verify my IP address and my modem mac address and they check out good. (I have an XP OS, IE, firefox, and opera web browsers, and a cable modem connection to the ISP - all three browsers cannot connect to the internet.) I can ping the yahoo and google websites and my loopback address, but cannot access these websites via my browsers. I look in the TCP/IP protocol properties and they're all set to automatically obtain the address. I also tried to manually configure the ip address, the sub mask, the dns servers, and the default gateway (first in the general tab, then in the alternate configuration tab) to the ones I found the network connections detail. I tried the ping, ipconfig, and netstat commands to try figuring out the problem but no luck.
Has anyone comes across this problem?

Any help and advices are much appreciated.
Thx in advance.

Appreciate some assistance.

Have a PC running W-Millenium. Going to format the hard drive (too many programs installed, virus problems, spyware, etc.) and reinstall the OS.

The current PC uses a cable ISP (Charter.net), and is connected to a router and a cable modem.

After installing the OS to a clean Hard Drive, installing drivers for video, sound card, etc., and some programs, the PC needs to be connected back to the router and the cable modem to establish an Internet connection.

Might be a super dumb question, but, which software should be installed first, that of the router, that of the cable modem, or does it matter?

Any guidance somewhere that shows the steps needed to connect the PC to both a router and a cable modem?

Alright...so I will start off by stating that I hate my apartment and how the cable is wired in the place. I have one line going into the apartment. It is in the living room. In order to get too any other point in the house I have too run cable lines around rooms and hook up too connections in wall that pass through the wall into the next room. I currently have my computer located in the dining room/kitchen area as I have a huge area and a small table. Too get too my computer with cable line it takes 3 connections to hook up too my modem (modem is last hook up). I would like to move computer too too bedroom, but too do so would take 6 different connections. Would I be losing "connectivity/bandwidth" by having 6 different connections or would it be better to get and hook a router up in living room and run a network line too the computer and cutting out those connections??? I would like to get the most out of my internet connection if you feel me.

Basic question? Will I get better connection using router over 6 connections??? Not sure about data/packet lose in the connections.

Okay, so this is basically my setup.

I'm using roadrunner's sb5101 cable modem...connecting this modem to a netgear hub with 4 ports.....

1 port receives the connection from the cable modem
1 port connects to my computer
1 port connects to my 360
1 port connects to my dlink router

here's my problem: all the connections work fine except for the dlink router; it doesn't seem to connect to the internet.

When I check the status tab, it says "dhcp client disconnected". I try the release IP and it says it was successful, but nothing happens. I try the renew ip and it says renew ip fail (obviously since it doens't have an ip).

So my question is, is it a crappy router? Am I missing something here?

I tried resetting the router to factory defaults by pressing the hard reset button in the back, and it sitll didn't connect.

Someone please help.

Oh, the reason i'm not connecting the modem to the router is beacuse the stupid router doesn't give me a static ip, so i'm banned from several sites and I need a static ip.

I have a cable modem at home and would like to use it for 3 computers on a small network. I know the cable company is not real keen on this (they said "no" - you have to pay more for each computer).

So i ordered a router. My question is, once i set up the router, will the cable company even know what I have done?

Thanks in advance for any help.


A:cable modem and new router

I set up a network about a week ago in the house before the kids (2) came home from college. This network was basically to just share the broadband internet R.R. It worked fine with until my son came home and hooked up. Since then all of a sudden it says that the LAN cord is disconnected on both of the computers and I have to restart every thing to get it to work again. Unplugging the router and plugging it back in usally does it. However it just does it again and agian. If I unplugg his computer and reset everything it works fine forever even with my laptop pluged in. I have checked with my son and he says that his XP firewall is off. I am all new at this networking stuff and at some point would like to share a printer and some files but for now ...any ideas on what may be happening this problem seems to happen about every 15min to an hour or so??? I am going to hook up my laptop on my sons cord right now and try that??

I have a Linksys WCG200-CC, which is an router/modem/wireless combo and I was wondering if it is possible to access the cable modem. I know how to access the user friendly network set up screen, but I am trying to enable more than just the 5 addresses ( has somehow locked it to this). If I can't expand from the router, can I use another router to give me more addresses?

OK, I'm running a Linksys cable modem with a Belkin router. The router is a 2.4g 802.11g wireless.

The problem is just that we have 5-6 laptops running at once, two are Macs, and they're all competing for some bandwidth. The cable and router go down frequently and have to be unplugged and restarted again and again.

This especially happens when someone is watching a recorded show on our media center PC (HP), through which the router and modem operate.

Can I even explain how annoying it is to have to constantly get up and unplug and then replug in the router and modem -- or yell through the house for whomever is sitting at the computer to do it -- and then have to wait while the connection is re-established? And this is nothing to say of the content that's lost when it happens.

Anybody have any ideas about this? Do I need a new modem AND router? Do they make them so they can handle more computers?

Thank you. Much appreciated!

A:Cable to Modem 2 router 2 wireless help PLS

Start by telling us the exact make/model of the modem and the two routers.
Here's a suggested configuration that should work, but it's based on the limited information we have to work with.

Here's what I'd do first, this is using the modem and the wired router.
Reset the router to factory defaults by holding the reset button down for 15 seconds with power on. The following procedure should get you a connection with any broadband modem that is configured to use DHCP for the router connection, such as cable modems, and many DSL modems. If you require PPPoE configuration for the DSL modem, that will have to be configured to match the ISP requirements.
Turn off everything, the modem, router, computer.
Connect the modem to the router's WAN/Internet port.
Connect the computer to one of the router's LAN/Network ports.
Turn on the modem, wait for a steady connect light.
Turn on the router, wait for two minutes.
Boot the computer.

When the computer is completely booted, let's see this.

Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

In the command prompt window that opens, type type the following commands one at a time, followed by the Enter key:


PING <computer_IP_address>

PING <default_gateway_address>

PING <dns_servers>


PING yahoo.com

Right click in the command window and choose Select All, then hit Enter to copy the contents to th... Read more

I have 2 pcs hardwired to a Linksys router that is connected to a cable modem. Both pcs get to the Ineternet fine. All I want to do is transfer files between the two computers and still be able to connect to the Internet via the cable modem from both pcs. I have a crossover cable, but not sure why I would need it if I'm connected to the router. I have zero knowledge of setting up networks.

A:Cable modem to Lynksys Router to 2 pcs - how?

If both computers are successfully connecting to the Internet through the router, you do not need the crossover cable.

Make sure you can ping the other computer's IP address. If this fails, just for testing, make sure you turn off XP's as well as any other firewall.

Make sure you can ping the other computers by name.

Make sure you have the same workgroup name (watch for trailing spaces)

For troubleshooting purposes, turn off XP's and completely uninstall any other firewall software. You can always add more complexity after you get it working.

With XP, make sure you have the same username and password as the person logging onto the other computers. The default setting for XP Pro is to require a password for network access.

More details about how to network XP can be found at:

There continues to be a lot of misinformation about needing NetBEUI or to changing the NetBIOS setting. You can ignore both. Installing NetBEUI to solve a networking problem will just mask a some underlying and potentially important misconfiguration with TCP/IP. The default NetBIOS setting works fine so there is no need to change that either. Just don't disable it.

My problem concerns my cable modem and my wireless router, I use a motorola surfboard cable modem. I got the Tv cable coming into the modem and by ethernet cable going to my linksys wireless broadband router. Which supplies a signal to my other two computer located upstairs. Also I got from the wireless router a ethernet cable to my computer. In the past I had this working. Working fine but lately it has a problem. I Found out that when I turn on my main computer down stairs the one connected hard wire that I lose the signal to the computers up stairs which are wireless. If I turn off my computer down stairs then the wireless system works. My system is Microsoft Windows Xp, HP Media center Edition Version 2002. I restored my computer hard drive back to the factory settings and I still am having the same problem. So if anyones has an answer I would be interested

I do a lot of P2P and assorted traffic. The router and modem die on a regular basis and it's really annoying. I have a linksys WRT54G v5 router and a Terayon TJ715 modem. It could be the cabling to my house, but I the connection is very unstable when doing P2P type activity.

I'm prepared to spend upwards of 700 dollars to get this fixed... but don't want to spend more then I need to.

What do you recommend.

A:Can I connect Cable modem to DSL router?

no. DSL and cable internet are two very different technologies. You'll need a standard router that you can use with any type of ISP. Then all you need is a cable modem or a DSL modem depending upon the type of service you have.

My Netgear FVS318 router is connected to an Optimum Online cable modem (dynamic IP). The router needs to be rebooted periodically (the internet connection stops). I think it is when the cable modem had gotten a new IP address. I'm not completely sure of that but it just happened and I noticed my modem a new IP address than what it had yesterday.

This happens every few days or so. The cable modem has a phone line that keeps working even when the internet is down, when I reboot the router the internet comes back up right away.

Would there be a setting in the router to help it adjust? or might there be a different problem?

No, you cannot use a modem/router as only a router.

You can use it as an ethernet switch and wireless access point, but you are going to need a router.

Im about to purchase a router for my house's new cable i-net connection. They charge 14.95 per extra isp, so i thought this would be the best way to do it. I got 2 questions. Now when the DHCP server onboard the router assigns ip address, are these unique to the network. I mean, when i video conference with my family on Netmeeting, and i give them the ip addy that shows up on my "ipconfig" utility, will it ring on all the other computers attached, or will it only ring on my computer. I know routers are usally good at splitting signals...but how good? Also, alot of routers claim to be say 4-port, but isnt one of these ports already taken up by the cable from the modem to the router, so in essence 3 avail. ports. Or would i be able to purchase a cross over cable. Plug one end in the modem and plug the other end in the "wan" or that seperate slot in the router, and have the 4 computer slots in the router for 4 computers? Whats the best way. Speed is sort of an issue, but im runing on a 14.4 cell connection right now, so anything will be better. Please let me know the best way to use a router. I have 5 computers i think that want to connect, but the only other routers i see after 4 port are 8 port. Please Help
